Abstract The Bose–Einstein condensate (BEC) is a fascinating state of matter predicted to
occur for particles obeying Bose statistics. Although the BEC has been observed with …

Order-disorder transition is observed in the quasi-one-dimensional anisotropic spin chain
antiferromagnet Ba Co 2 V 2 O 8 in magnetic fields along the magnetic easy c axis below the …

Magnetic correlations of two isostructural quasi-one-dimensional (1D) antiferromagnetic
spin-chain compounds Sr M 2 V 2 O 8 (M= Co, Mn) have been investigated by …

We report a neutron diffraction and muon spin relaxation μ SR study of static and dynamical
magnetic properties of BaCo 2 V 2 O 8, a quasi-one-dimensional spin-chain system. A …

In this study, a spin-1/2 extended anisotropic XY chain has been introduced in which both
time reversal and SU (2) symmetries are broken but Z 2 symmetry is preserved. Magnetic …

Magnetic and topological properties along with quantum correlations in terms of several
entanglement measures have been investigated for an antiferromagnetic (AFM) spin-1/2 XY …

In the present paper we discuss the rich phase diagram of S= 1 2 weakly coupled dimer
systems with site dilution as a function of an applied uniform magnetic field. Performing …

Building on recent NMR experiments [A. Orlova et al., Phys. Rev. Lett. 118, 067203 (2017).
PRLTAO 0031-9007 10.1103/PhysRevLett. 118.067203], we theoretically investigate the …

The field-induced antiferromagnetic ordering in systems of weakly coupled S= 1/2 dimers at
zero temperature can be described as a Bose-Einstein condensation of triplet quasiparticles …

We consider the quantum Ising chain with uniformly distributed random antiferromagnetic
couplings (1≤ J i≤ 2) and uniformly distributed random transverse fields (Γ 0≤ Γ i≤ 2 Γ 0) …
